ROTATE the plastic cap on the CYLINDER VALVE until
the arrow points out through the gap in the valve shroud.
PULL the lanyard out, then upwards. The cap will lift off
the valve. Do not use tools. Leave the cap hanging down
from the valve while the cylinder is in use.
Assembly on the gas cylinder
Make sure that:
-
all taps on the consuming appliace are closed;
-
the connecting pipe to the appliance is correctly fitted;
-
The Quick-on regulator handle is in the closed position (fig. 3).
With no flame on, remove the seal cap on the cylinder automatic valve, place the
Quick-on onto the automatic valve and push down firmly and vertically. You will hear a
“click” sound which means the regulator is securely latched (fig. 4).
Note: Quick-on is so designed as to prevent it from being fitted to the valve, unless the
regulator handle is in the closed position; therefore, never attempt to mount or dismount
it, if the handle is not in this position.
Operation
Once the Quick-on is correctly mounted on the valve, gas supply is possible by turning
the regulator handle upwards (counterclockwise).
To shut off the gas supply, reverse above procedure; an arrow engraved on the handle
indicates the closing direction (fig.3).
Symbols engraved on the bonnet show how to operate the regulator handle.
CAUTION: if you are unable, to open the regulator handle, this means that your Quik-
on is not correctly connected to the valve. Do not force the handle to open, instead start
again the operations described above in 3.
Replacement of a cylinder
Make sure that:
-
all taps on the consuming appliance are in the closed position.
-
the Quick-on regulator handle is in the closed position.
Then, dismount the Quick-on by pressing horizontally on the handle and pulling
upwards at the same time (fig.5).
Do not attempt to carry out this operation with the regulator handle in the open position.
